My 1989 Jayco pop-up that I am modifying has the same approximate dimensions (7X10) and the same 12" wheels. It has 2,205 lbs GVW listed on the VIN tag and the original rig weighed in at about 1,400 lbs. It is constructed of 3" C-channel. Your frame should be very similar and should easily carry your planned weight.
